Sunny_sXe [5.5K]

Answer: The correct options that apply to the food web are-

Food webs are a group of connected food chains.
Arrows in a food web go from the organism that is being eaten to the organism that is eating it.
Arrows in a food web represent the flow of energy in a food web.
Food webs show all of the eating patterns in an ecosystem.

A food web is an interconnected network of different food chains representing flow of energy and matter within an ecosystem. The different arrows in a food chain represent organisms being eaten by other organisms, thereby representing flow of energy. It also represents that an animal can consume more than one food type.

Community ecologists study the factors that determine the abundance of different species. The Abundance of three algae species (

Tema [17]

Answer:

Explanation:

Given that:

The abundance of three algal species in Lake A is now represented by the vectors:

[97, 84, 43] and [100, 80, 50]

Now if we look at Lake A, the change occurring in the vector of algae species can be determined as:

a = [100 -97, 80 - 84. 50 - 43]

a = [3, -4, 7]

Thus, the magnitude of that change is:

$|a| = \sqrt{(3)^2 +(-4)^2+(7)^2}$

$|a| = \sqrt{9+16+49}$

$|a| = \sqrt{74}$

$|a| =8.6 \ mg/mL$

The abundance of three algal species in Lake B is now represented by the vectors:

[25, 59, 22] and [20, 63, 15]

At Lake B, the change occurring in the vector of algae species can be determined as:

b = [20 -23, 63 - 59. 15 - 22]

b = [-3, -4, -7]

Thus, the magnitude of that change is:

$|b| = \sqrt{(-3)^2 +(4)^2+(-7)^2}$

$|b| = \sqrt{9+16+49}$

$|b| = \sqrt{74}$

$|b| =8.6 \ mg/mL$

Hence, for both Lake A and B, the magnitude of change is the same.

Compared to its surroundings, the concentration of solutes is low inside a cell so, the cell is in a hypertonic, hypotonic or is

Kazeer [188]

Answer:

The cell is in a hypertonic solution.

Explanation:

The solution is hypertonic because the amount of solute(s) is higher outside of the cell than it is inside the cell, so the solvent (e.g. water) would move from the cell to the solution in order to obtain equilibrium between the two.
